AG Kareena is a star in the Kareena constellation. It is classified as a Luminous Blue Variable (LBV), one of the brightest stars in the Milky Way. At a distance of 20,000 light-years from Earth, interstellar dust means that the star is not normally visible to the naked eye; Its brightness varies randomly between 5.7 and 9.0.
A star is surrounded by a nebula formed by matter ejected 0.4–1.2 pc from the star. The nebula contains about 15 solar masses, all of which are hardened to be lost from the star 10,000 years ago. The interstellar medium around the star has an empty chamber 8.8 pc wide, which is formed by the stellar wind that is emitted at the star ‘s initial points
G AG Kareena is in a transition phase between a large class O blue supergiant and a Wolf-Wright star, experiencing very unstable and random pulsations, occasional large eruptions and rare large eruptions.
